Wave-optics phenomena in gravitational lensing occur when the signal's wavelength is commensurate to the gravitational radius of the lens. Although potentially detectable in lensed gravitational waves, fast radio bursts and pulsars, accurate numerical predictions are challenging to compute. In this talk I will present recent advances on numerical methods to tackle this problem and their...
In the Standard Model (SM), the electroweak phase transition – which marked the breaking of the $SU(2) \otimes U(1)$ symmetry through the Higgs mechanism – is predicted to have been a crossover. Several extensions of the SM, however, can realize it as a first-order phase transition (FOPT), which might lead to successful electroweak baryogenesis in the early universe.
A FOPT proceeds through...
Self-interacting dark matter (SIDM) model with a density spike can potentially solve the final-parsec problem. Hence, we probe this model using the gravitational wave background data from pulsar timing array. We found that our results for the SIDM model parameters are consistent with the existing literature.
